Hi Brad, Thanks a lot for the clarification, it worked as I followed your steps. However, I'm stuck at a simple OWL reasoning as I extend the same instance data. - Here's my updated instance data *@prefix : <http://kg.cts.com/ <http://kg.cts.com/>> .* *@prefix foaf: <http://xmlns.com/foaf/0.1/ <http://xmlns.com/foaf/0.1/>> .* *@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns# <http://www.w3.org/1999/02/22-rdf-syntax-ns#>> .* *@prefix rdfs: <http://www.w3.org/2000/01/rdf-schema# <http://www.w3.org/2000/01/rdf-schema#>> .* *@prefix owl: <http://www.w3.org/2002/07/owl# <http://www.w3.org/2002/07/owl#>> .* *@prefix org: <http://www.w3.org/ns/org# <http://www.w3.org/ns/org#>> .* *:A rdf:type org:Organization .* *:LeadershipRoles a org:Role .* *:AdminRoles a org:Role .* *:ROLE1 a :LeadershipRoles .* *:ROLE2 a :LeadershipRoles .* *:ROLE3 a :AdminRoles .* *:CEOType a org:Membership ; * * owl:equivalentClass [* * a owl:Restriction ;* * owl:onProperty org:role ;* * owl:someValuesFrom :LeadershipRoles* * ] .* *:139137 rdf:type foaf:Agent ;* * rdfs:label "139137" ;* * org:memberOf :A ;* * org:hasMembership [a org:Membership; org:role :ROLE1,:ROLE3] .* *:139138 rdf:type foaf:Agent ;* * rdfs:label "139138" ;* * org:memberOf :A ;* * org:hasMembership [a org:Membership; org:role :ROLE3] .* *- *As per the above assertions, I should get :139137 to have :CEOType membership if I make this SPARQL query. But I'm not *prefix : <http://kg.cts.com/ <http://kg.cts.com/>>* *prefix foaf: <http://xmlns.com/foaf/0.1/ <http://xmlns.com/foaf/0.1/>>* *prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns# <http://www.w3.org/1999/02/22-rdf-syntax-ns#>>* *prefix rdfs: <http://www.w3.org/2000/01/rdf-schema# <http://www.w3.org/2000/01/rdf-schema#>>* *prefix owl: <http://www.w3.org/2002/07/owl# <http://www.w3.org/2002/07/owl#>>* *prefix org: <http://www.w3.org/ns/org# <http://www.w3.org/ns/org#>>* *select distinct ?who* *where* *{* * ?who org:hasMembership :CEOType .* *}* - However, I am getting right result if I search for exact type i.e. *prefix : <http://kg.cts.com/ <http://kg.cts.com/>>* *prefix foaf: <http://xmlns.com/foaf/0.1/ <http://xmlns.com/foaf/0.1/>>* *prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns# <http://www.w3.org/1999/02/22-rdf-syntax-ns#>>* *prefix rdfs: <http://www.w3.org/2000/01/rdf-schema# <http://www.w3.org/2000/01/rdf-schema#>>* *prefix owl: <http://www.w3.org/2002/07/owl# <http://www.w3.org/2002/07/owl#>>* *prefix org: <http://www.w3.org/ns/org# <http://www.w3.org/ns/org#>>* *select distinct ?who* *where* *{* * ?who org:hasMembership/org:role/rdf:type :LeadershipRoles.* *}* *RESULT: * who<http://kg.cts.com/139137> <http://localhost:9999/bigdata/#explore:namespace2:<http://kg.cts.com/139137>> What am I doing wrong ?
